1、php-fpm 配置文件里 rlimit_files的值 要与系统的打开连接数一致PHP教程
1)查看系统文件打开连接数PHP教程
[root@iZ94eveq0q4Z ~]# ulimit -n
65535PHP教程
2)查看一下php-fpm 配置文件里 rlimit_files的值 PHP教程
; Set open file descriptor rlimit#rlimit设置打开的文件描述符
; Default Value: system defined value
rlimit_files = 65535
如果两个值不一样,则要设置为一样PHP教程
方法如下：PHP教程
3)设置系统打开文件连接数PHP教程
[root@hotdata ~]# ulimit -HSn 65535
[root@hotdata ~]# ulimit -n
65535
[root@hotdata ~]#PHP教程
设置好后重启php-fpm服务PHP教程
2、 request_terminate_timeout = 0 设置为0PHP教程
; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the ‘max_execution_time' ini option
; does not stop script execution for some reason. A value of '0′ means ‘off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
request_terminate_timeout = 0PHP教程
因为这个参数会直接杀掉php进程,然后重启php进程,这样前端nginx就会返回104: Connection reset by peer.这个过程是很慢,总体感觉就是网站很卡PHP教程
nginx可能出现502
recv() failed (104: Connection reset by peer) while reading response header from upstreamPHP教程
3、request_slowlog_timeout这个配置不要开启PHP教程
之前服务器上开始了这个参数,并且设置如下：PHP教程
request_slowlog_timeout = 10导致图片处理每次都失败,每次都是502错误.PHP教程
错误信息如下：PHP教程
Nginx的错误信息：
2015/12/28 16:20:23 [error] 649#0: *9862 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 163.177.69.13,
